Complete Question Explanation
StrengthenX—CE. The correct answer choice is (D)
The causal relationship here is that the rash was caused by prolonged contact with telephones. We are asked to find an answer choice that does not support this relationship.
Answer choice (A): This answer choice supports the conclusion by showing that some people are likely to be allergic to the materials used to make phones.
Answer choice (B): This eliminates the possibility that other devices could have caused the one-sided rash, thus strengthening the argument.
Answer choice (C): This strengthens by showing that most patients were in frequent contact with phones (so more exposure to cause).
Answer choice (D): This is the correct answer choice. The fact that most people use a phone does not help to link phone usage to the rash observed.
Answer choice (E): An increase in phone usage could help to explain the new appearance of rashes, so this answer helps the argument.
